Can you have some code demonstrating it? Well such per-board driver would handle the board-specific init, like configuring the hub GPIO (as Richard has to do so on mx6q) or flick some other GPIOs, configure registers etc. You can not depend on a bootloader to do such init for you, even though the bootloader should do it and should do it right. > > Regards, > Shawn Best regards, Marek Vasut -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
